the said corrugated stripscanbe rapidly and easily deformed in order to accommodate and retain the'balls correctly' in theiroperative positions.

According to `one of the preferred methods portion-being pressed inwards after the cage has been put into position on the balls, yso

as to cause a permanent'change in the shape of the cage and to 'complete the housings for the balls in order to retain same in their final positions. Y,

Y The said process enables suitably vshaped tools to be used for obtaining an accurate lper- 1 manent change of shape in the M shaped loops or sections, the saidtools being easily and rapidly ycentered on the middleorcentral V portions of the said loops, j f Y Obviously it lis'sutlicient that points of the V portions inthe Nl shaped separating loops in the strip should be exactly located andl calibrated to obtain the automatic and correct distribution of the balls between their tracks 35. when assembling thel` bearings, something-'' which rcannot be obtained by the hitherto knownmethods, particularly in case-of the assembly of double row' ball bearings, in

which the bended parts of the bands holding 40 the balls are located opposite each other and very close together and to the middle or cen- 1 traly plane of thebearing."

In the case ofsuch double row ball bearings,

the process according to the invention'em ables the axial length 'of the bearings to he reduced to the minimum Value .enabling a satisfactoryy operation, and practi-V cally the distance between theinid'dle or cenl tial planes of each of the .tracks can be made y equal to twice the radi-lis the.b alls?" inA hearing of the radial canbe shapedff 'Y l f, According to the inVentiom-"cages arev usedy l Veach composed oa corrugated strip l of Vmaterial adapted to be deformedjand which "i creased naturally chefvvi/orking'play and. of mountingor assembling ball bearings nifthe'play vcorresponding to the different dis- .i
